Lukas Matena a95509ce36 Changed internal coordinates of drain holes
Drain holes reference position was saved slightly above the mesh to avoid problem when the hole is placed on flat or nearly flat surface
The depth of the hole was internally bigger than what the user has set to compensato for it
However, this leads to problem with scaling and makes reprojection of the holes on the mesh complicated

This commit changes the reference point to the point on the mesh and the extra elevation is handled when rendering and drilling the hole.
The change is reflected in 3MF drain holes versioning so that old 3MFs are loaded correctly.
Reprojection on the mesh after reload from disk/fix through netfabb has been enabled.
